One of my chargers is designed to blink red and green as the battery comes close to being fully charged. After a while, the light remains green. Have you tried just leaving the battery in and let it keep charging and flashing for a couple of hours to see if the light stops flashing?
Just a thought: perhaps the battery is defective and won't accept a full charge.
